LUBRICATING JOURNAL-BOX.

Specification of Letters Patent.

Patented Feb. 24, 1914.

Application filed February 25, 1910. Serial No. 546,028.

To all whom it may concern:

Be it known that I, IWAN Szo'r-Cznrnn, a subject of the Emperor of Russia, residing at Nowowiejska 16", Warsaw, in the Empire of Russia, have invented certainnew and useful Improvements in Lubricating Journal-Boxes, of which the following is a full, clear, and exact description.

This invention relates to lubricating journal boxes, and is adapted for use on all kinds of vehicles, the essential feature of the invention consisting in the provision of a lubricating pad which by means of a spring is pressed against the journal and is located at the bottom of the axle-box which is constructed to serve as an oil reservoir, while the lateral escape of the oil from the bearing along the axle is prevented by means of an oil removing device.

The accompanying drawings illustrate various constructional modifications of apparatus in accordance with this invention, wherein- Figures 1 and 2 show respectively in longitudinal section and in transverse section on the line A-B of Fig. 1 one form of carrying the invention into practice, while Figs. 1 and 2 2 and 2 are similar views illustrating other forms of apparatus in accordance with this invention.

In Fig. 1 the reference numeral 1 indicates the receptacle for the lubricating pad, this receptacle being approximately rectangular and having arranged in it the lubricating pad by means of which the journal is supplied with oil. The oil is supplied to the receptacle 1 and consequently also to the lubricating pad through slots 4:, provided in the side of the receptacle. For the purpose of retaining the lubricating pad in position laterally there is provided on the receptacle 1 a groove shaped projection 2. The receptacle 1 together with the lubricating pad are pressed against the journal by means of a spiral spring 3, which is located between the receptacle 1 and the external rib 5, which serve for the guidance and strengthening thereof. The lubricating pad is inclosed in front by means of a strap 6 of zinc or copper, which is inserted into the upper front of the receptacle 1 and which also assists in protecting the receptacle against excessive wear. The lubricating pad may consist of wool, felt or any other suit able absorbentmaterial.

The oil-removing device, shown in Fig. 2,

which prevents the escape of the oil from the axlebearing-along the axle, consists in this case of a rectangular disk 6, which segmentally embraces the axle and is cut away and a metallic body 7 arranged beneath it. This metallic body 7 is furnished with two parallel tongues 8, the sharp edges of which are pressed against the axle by means of the spiral springs 11 which are guided by the pins 10 and bear against the metal body 7. The springs 11 bear at their other ends against a rod 12 arranged beneath the oil-removing device. Between the thin plates, or tongues 8 there is arranged a lining 9. The oil wiped away by the tongues 8 is returned to the axle-box by means of the openings 15 provided in the walls ofthe casing. This arrangement, by means of which the oil is always forced to return into the axle-box, which serves as an oil-reservoir prevents any waste of oil and enables the same to be repeatedly used throughout a prolonged period of time. The aperture 16 which can be closed by means of a screw cover serves for the supply of oil and for the control of the oil-level within the axle-box.

In the constructional modification shown in Fig. 1 the lubricating pad is formed of a number of layers 2 of felt or other suitable material held together by means of bolts 3 and compressed between two outside metallic disks 1, one of which is provided with a projecting angle-iron 5, by means of which the pad is engaged with a corresponding rib on the axle-box casing. The felt layers 2 are arranged between two wooden blocks 6, which are provided at the base with cylindrical recesses for the reception of the springs 8.

In the constructional form of oil-remover shown in Fig. 2 the upper packing disk 10 has the form of a metallic disk provided with a lining 20 attached to it by means of a screw 19. Bolts 12 which are screwed into the body of the oil-remover pass through the flanges of the disk 10 and have mounted on them spiral springs 13 the lower ends of which bear against the flanges of the disk 10 while their other ends bear against the pins 17 or 18. By means of this arrangement the oil-remover 11 is spring pressed against the axle. The oil-removing body is again furnished with thin plates or tongues 14, the edges of which bear against the axle and betweenwhich there is arranged a lining 15.

In the constructional form illustrated in Fig. 2 the oil-removing device has the form of a divided disk Q'the lower half of which I theseguide pieces 7 there bear spiral is adjustably guided in the upper half by means of the groove 4 and the spring 5. In a recess in the center of the lower half there is fixed 'by means of screws 3 the oil-removing device proper which is again provided. with thin plates or tongues l. The upper portion-of the disk 2is furnished at its edges with guide pieces 7 which are attached 'to it by means of screws 6 and the lower ends of which are bent at right angles. Against springs 9 which are inserted in recesses provided in the lower half of the disk 2 and the upper ends of which are connected by means of screws 10 with the disk 2. By means of the arrangement just described the lower part of the, disk 2 and the thin plates 1 are springpressed against the axle.

In the constructional form illustrated in Fig. 2 the oil-removing device comprises a disk 1 completely embracing the axle and furnished with a bed-plate 5 attached to it by means of screws 6. In apertures ar ranged in this bedplate and in recesses 4 in these apertures there are guided bolts 2, the upper ends of which have the form of thin plates or tongues provided with sharp edges. These plates or tongues are pressed against the axle by the action of the spiral springs 3. To enable these plates to be drawn downward when the disk is to be placed in posi-- tion, the bolts are connected with each other by means of a wire 7 which passes through perforation provided in them for this purpose.

The main advantage of these constructional forms of the lubricating device and of the oil-remover consists in the fact that even when the upper bearing cap becomes worn away, the uniform pressure of the lubricating pad against the journal as well as the removal of the oil and the return thereof to the axle-box are notwithstanding insured.

Claim: i

In a journal box having a journal seated therein and having means for oiling the journal, a plate non-rotatably mounted in said box and having an arcuate aperture therein of less than 360, said journal being fitted into said aperture with its top and lateral surfaces in contact with said plate, metal tongues having sharp edges contacting the under surfaces of said journal for removing surplus oil therefrom, said tongues being resiliently held in contact with the under surface of the journal, and a member of fibrous material disposed between said tongues and having a concaved surface contacting the under surface of the axle for limiting the pressure of the tongues against the axle.

In witness whereof, I subscribe my signature, in presence of two witnesses.
